7014 ACD/HCP4ADBC Bearing Product Overview & Core Advantages
The 7014 ACD/HCP4ADBC is a precision duplex angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This matched back-to-back (DB) arrangement is preloaded to Moderate / Class C specifications, providing superior stiffness and rotational accuracy. Its construction with a ceramic ball and phenolic cage enables high-speed operation up to 36,000 rpm while effectively handling combined radial and axial loads. This bearing is ideal for high-precision, high-reliability machinery where rigid support and minimal runout are critical.

7014 ACD/HCP4ADBC Bearing Structural Features & Performance Benefits
- High Rigidity & Accuracy: The duplex back-to-back (DB) arrangement and moderate preload (Class C) create an extremely rigid bearing system that minimizes axial and radial deflection, ensuring precise shaft positioning and excellent running accuracy.
- Superior Load Capacity: Engineered to withstand significant combined radial and axial loads simultaneously, thanks to the 25° contact angle and robust design with a high dynamic load rating of 17,842 lbf.
- Exceptional High-Speed Performance: The combination of lightweight ceramic balls, which reduce centrifugal forces, and a phenolic resin cage allows for a very high limiting speed of 36,000 rpm. This makes it an ideal high-speed bearing solution.
- Precision & Stability: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, guaranteeing consistent, high-performance operation in precision applications.
